Chunks of concrete fell off the overpass on August 31. No one was hurt, but officials are investigating to determine the cause of the incident.

The 3, 4 and 5 lanes of the freeway will be closed on Tuesday between 10 a.m. and 5 p.m. from just north of the Blaine-Third Street overcrossing to just south of the 60-91-215 interchange.
The connecter to the westbound 91 Freeway will also be closed.
